Application filed June 17, 1.919. Serial No. 304,774.

To all whom it may comer n:

Be it known that I, HOSMER BLUM, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented certain new and useful 1m rovements in Meters, of which the followlng is a specification.

The present invention relates to that class of meters which are operated by' the fluid which they measureon the same passc apable of operation by a very low head pressure, thereby adapted foruse in connection with the measuring of light or heavy fluids or gases or the'like. A further object .is to provide a construction wherein there is provided considerable area acted on by the fluid in passing therethrough which will insure a positive operation of the apparatus under a very little head pressure; a further object is to provide an apparatus particularly of the multi-cylinder and piston type wherein the fluid supply to and from the cylinders is controlled by a novel form of valve, directly operated by the movement of the piston in measuring the fluid charge admitted into and discharged therefrom. A'still further object is to provide a novel form of adjusting means wheretlon.

reference is directed to the accompanying by the fluid measuring meanswmay be ad'- justed to operate in synchronism with any form of registering means desired, thus providing a device with which may be associated any suitable form of'indicating mechanism constructed for this purpose. With the above mentioned and other objects in View, the invention consists in the novel construction and combination of parts hereinafter described illustrated in the accompanying drawings, and set forth in the claims hereto appended, it being understood that various changes in the form proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sac 'rificing any ofthe advantages of the inven- To" more fully comprehend the inyention,

drawings, wherein,

& Fig. is-a view in broken side elevation,

of the preferred embodiment of my invention.

Fig. 2 is a top plan view.

Fig. 3 is a transverse sectional view taken on the line '33, Fig. 1, viewed in the direction of the arrows.

Fig. 4 is a transverse sectional view taken on the line 4- 1 of Fig. 1 viewed in the direction of the arrows.

Fig. 5 is an enlarged detailed view in cross-section of the controlling valve, and

Fig. 6 is a view in detail of the piston stroke varying means.

Referring more particularly to the several views of the drawings wherein like characters of reference designate corresponding parts, the numeral 1 indicates an open-topped cupped shape chamber or base provided in the center of its bottom wall with the threaded openingQ, and also provided with the supporting l'ugs3. Closing the upper open end of said member 1 is a cover member 4 attached thereto by the screws 1' provided on its under surface 5 with a plurality of circumferentially disposed cylinders 6 depending vertically within the chamber of the member 1, as in 'Fig. 1 of the drawings. The wall 5 at the upper end of each of said cylinders is providedwith an inlet and outlet port 6, and upwardly from said wall 5 extends a circular flanged wall 7, Figs. ,1 and 5 of the drawings, said wall provided at one side of said cover plate with a fluid outlet opening 8 which connects with an outlet chamber 9 from which leads a threaded discharge opening 10. Disposed diametrically opposite said threaded discharge opening 10 is a corresponding fluid inlet opening 11, which terminates in a fluid receiving chamber 12 of, annular-formation lying between the upper surface of the plate 5 with 'universal movement within a bearing 15,

said bearing being disposedat spaced intervals on the peripheral edge of a circular plate 16, fulcrumed in its center for universal movement through a 'ball and socket joint 17 on a stud or standard 18, having adjustable threaded connection with a Supporting plate 19 positioned within the base of the member 1. The plate 16 is provided with one or more openin s 20 through which extend the guiding stu s or bolts 21, de-

discharged from successive cylinders by a,

hereinafter described valve movement will cause the operation of the pistons 13 within the cylinders and which operation will in turn impart a wabbling movement to said plate 16. Upwardly from the center of said.

plate 16, immediately. above its fulcrum point extends a valve operating arm 23, the upper end of which, due to the operation of the plate 16, is adapted to travel in a circle and cooperates through a universal connec tion 24, Fig. 4 of the drawings, with an offset-crank 25, secured to a vertically disposed shaft 26. The shaft 26 is rotatably mounted in a bore 27 formed centrally of a valve supporting plate 28, resting in an annular depression 29 in the upper surface of the wall 5, and the peripheral edge of said plate is adapted to lie immediately beneath the inner peripheral edge 30 of the flange 7'. The plate is provided with ports 31 overlying and registering with the ports 6 in the wall 5 and also with ports 31 registering with the interior of the chamber 1 within which the parts 14,16, 20 and 23 operate, permitting the entire chamber 1 to become filled with fluid which serves as a lubricant for the various working parts. Resting on the upper surface of the flange 7 is a plate 32 provided in its center with an opening 33, said plate being secured to said flange by suitable fastenings means 34, said plate separating the chamber 9 from the annular cham-' ber 12, except through said opening 33 which is valve controlled, as hereinafter described. A filtering screen 35 held at its upper edge between the edge 30 of the flange 7 and the annular flange 36 on the plate 32 rests at its lower edge in the annular depression 29 in the wall 5, Fig. 5 of the drawings, and is retained therein by the friction of the pe ripheral edge of the plate 28, said screen preventing the passage of sediment into the operating mechanism of the present apparatus.

The shaft 26 at its upper end is provided with an offset crank 37 disposed at an angle of 90 degrees from the crank 25, and upwardly from said crank 37 extends the crank pin 38 receivable within a suitable opening 39 disposed centrally of a valve plate 40. The plate 40 is provided with suitable fluid outlet ports 41 and the peripheral edge 42 thereof is formedwith a flat under-surface adapted to rest on and operate in frictional contact over the upper surface of the plate 28 5 of the drawings.

Said peripheral surface is formed at its upper edge with the upwardly inclined packing supporting surface 43 on which rests the annular flexible packing 44, held in position by an annular ring 45, and the free edge thereof adapted for forcing by the fluid pressure within the chamber 12 into frictional contact with the under-surface of the plate 32 to prevent leakage between the upper surface of the valve and the underside of said plate 32.

The upper wall of the covermember 4 is provided with a central aperture which is closed by a dividing plate 46 which forms a portion of the top wall. of the chamber 9 and above which is mounted any suitable type of indicating mechanism which forms no part of the present invention. The indicating mechanism is contained within the housing 47 secured to the member 4 by screws 48, which retain the plate 46 (in position, said housing 47 being provided with an opening 49 in its, top, adapted to be covered bya pivoted closure plate 50, the-raising of which permits reading of the meter. The tapered end 51 of the crank pin 38, Fig. 5, operates the indicating mechanism designated jointly by the numeral 52 through a gear'train 53, ,Fig. 1 of the drawings, said indicating mechanism and gear .train forming no part of the present invention, the same is not here described in detail as any suitable form of mechanism for this purpose may be employed in connection ,1

with the present meter.

Assuming the parts to be in a position as in Fig. 5 of the drawings, the fluid under pressure being admitted into the inlet 11, said fluid will pass throughthe screen 35 and downwardly through the openings 31, and 6', which are totally or partially uncovered, due to the position of the valve 40 and the pressure of the fluid will cause a downward movement of the pistons within the cylinders into which said fluid passes. The fluid in the cylinders, the openings 31 and 6 of which lie within the peripheral edge 42 of the valve 40 will be expelled therefrom by the movement of their associated piston and pass through said openings 6' and 31, the opening 33 in the plate 32, through the opening 8 into the chamber 9, and discharge from the outlet 10. This operation of the pistons by the fluid admitted under pressure causes a wabbling of the plate 16 and an annular movement of the free end of the member 23, which moves the valve 40 in a circle alternately covering and uncovering successive openings 31 in the plate 28. The valve in its movement being capable of free rotation about the crank pin 38. Each successive revolution-of said crank pin 38 in turn operates the indicating mechanism 52, thus it will be apparent that the fluid volume operating the pistons 13 is measured in passing through the present ap-r paratus and on the setting of the mechanism, as hereinafter described, in synchronism with the mechanism 52. It'will also be apparent that by providing a packing 44, which is seated by the fluid pressure in the chamber 1 that the friction between the upper surface of the valve 40 and the under-face of the plate 32 is reduced to a minimum during the maintaining of the fluidtight-joint between said surfaces.

To regulate the operative stroke of the pistons 13 and to obtain a proper setting of the apparatus, the stud or standard 18, as heretofore described, is adjustable by a threaded connection within a threaded bore 54 in the center of the plate 19. The openin 2 in the bottom wall of the member 1, is adapted to be closed by a plug 55 positioned therein from the interior of said member 1, the plug having a central opening there- ,through and into which extends the squared end 56 at, the bottom of the standard 18, said squared end being received in a corresponding recess 57 in a key plate or member 58 positioned within the opening in said plug,

the key plate being held in its adjusted position by a suitable clamp ring 59, access to which and to the slot 61 in the key plate 58 is precluded by the employment of a particular style ofclosure member 60, positioned over. the outer end of the opening in the plug 55 and adapted to close the same, 'said disk 60 being preferably of the fragile non-replaceable type which when tampered with is only renewable by those having charge of the meter.
